Reviewing auto-generated spelling corrections
Spelling corrections that are automatically generated by the Token and Phrase Spell Correction job are assigned one of the following status values:
-
Auto
There are three values for confidence level:
Value Confidence Label 0
low confidence
Pending
0.5
median confidence
Auto
1
high confidence
Auto
No action is required on these results, but you can edit them if you wish. -
Pending
The confidence level is ambiguous, and the result must be reviewed by a user before it can be deployed. It will only be moved from the
_query_rewrite_stagingcollection to the_query_rewritecollection when its status has changed to "Approved" and it has been published.
-
Navigate to Relevance > Rules. The application displays the Query Rewriting screen.

Select Misspelling Detection. The application displays the Misspelling Detection screen.
Notice the Status facet on the left. Click Pending to view only the items that need review.
-

icon next to the spelling correction. -
In the Status column, select either "Approved" or "Denied".
Optionally, you can also edit the spelling correction itself.
